No problem. I think my neurons are less rusty because of my perverse
hobby:-). I've actually compiled the Blanca Demo stuff in the last year and
I try to keep up with evolution of Pooma 2 with the thought that I will
sometime get back to using it. John, Don and Jean have actually been doing
some work on the source code base in the last year.
Also, the Blanca Demo project and it's progeny is the only Blanca related
source code base that to my knowledge ever used Pooma 2. And supposedly, the
Blanca project is dead and unlikely to use anything that we ever did.
